So someone with a blown engine mentioned a few pages back that a tech said their Bronco had zero coolant in it when it was brought in. I decided to check my reservoir (nov build date, 600 miles) and I'm a little concerned that its sitting below MIN. Is this thing burning coolant already?

There are reports that they were coming low on coolant from the factory for whatever reason:
https://www.bronco6g.com/forum/threads/low-coolant-level-at-delivery.33097/

It's even on the Delivery Checklist that is being maintained. It boggles my mind that something like "low coolant" is not part of the PDI, but here we are...

Burning oil I can understand for some new engines, given the piston rings may not seat for a bit. Burning coolant is a much more serious concern. Have you verified there’s no evidence of a coolant leak anywhere in your engine bay?

No signs at all, parking spot is bone dry 🤷‍♂️

IF there is a head porosity issue, that might account for the loss of coolant. Porosity issues have happened with most manufacturers that use cast heads. I was thinking this a few pages ago, but if there is a void in the head next to a valve stem, that could cause a failure of the valve like we are seeing. It might also account for the loss of coolant.

Having the vehicle go down is definitely a bad thing, but at least they are happening early so there is no question of warranty claim issues. Hopefully we figure shit out soon.

My 2.7 is 10/21 and we took delivery of it 12/4 and have 2800 miles on it thus far. Just did an oil change in the garage last week on it.

Good point. the old castech heads on my 2004 GMC 5.3 got pitted and started eating coolant. just about blew that engine. I caught it..... Had to change the oil every 100 miles or so just to restart the timebomb

I found the actual website for the Lima Plant here:
https://www.at.ford.com/en/homepage/news-and-clipsheet/plants/na/lima-engine.html

Which had a link to the "State of the Plant Newsletter" here:
https://www.at.ford.com/en/homepage...ive/2022/1/state-of-the-plant-newsletter.html

There was mention of a known valve issue in this newsletter

I sent an email with a link to this thread so they could be aware of the information gathered here. I'll let you guys know if I get a response...
No surprise but I have not received a response to my email. It just would be really nice for @Ford Motor Company to.
1) Make some acknowledgement to this issue (as it obviously was a known issue based on their own newsletter)
2) Give some information on their findings of the cause
3)If there are such findings give an estimate of what date ranges may be affected or when the above mentioned changes went into effect.

Sorry I didn’t read all 86 pages of your thread. Have these pics been posted for you mechanical sleuths? There were also few videos I’ve posted in the past of Ford techs showing the 2.7 destroyed as well but looks like they have been wiped from the interwebs. 🤔

I don’t think you can assume it is burning/losing coolant if you don’t know if it ever had a full level of coolant present. I don’t want to point at the mechanics who are doing PDI’s as missing fluid levels. But their excuse will be that they are too busy, or forgot. Each car we buy should come with a PDI inspection checklist, that the mechanic and service manager sign off on. Just saying.
